Product Overview

The Omron FINS Serial driver exchanges data between OPC clients and Omron FINS protocol-compliant PLCs via RS-232 or RS-422. It also supports Sysmac Link operation to access additional PLCs via Sysmac Net. Kepware automatically optimizes data acquisition based on client demand and ensures data integrity through extensive error handling.

  • Added Chinese language support.



  • Added Japanese language support.



  • Corrected an issue where the driver would produce a syntax error during tag validation if the data type was not supported. Some clients add items with a set data type regardless of the address. The driver now responds with bad type, allowing the driver library to validate again with the default type.


  • Added the ability to select the behavior when writes are issued to TS and CS addresses (when the PLC is in Run Mode). Previously, these writes would fail and an error would be logged. Now, options exist to set the PLC to Monitor Mode and perform the write, or to set the PLC to Monitor Mode, perform the write, and then reset the PLC to Run Mode.


  • Added support for the CJ2 Model.
  • Added the reporting of device-level error conditions and detection of network relay error frames. We now output the following error messages instead of posting "Device not responding" messages:

     • Network relay error.[Net Addr, Node Addr: '0x00, 0x3A'], [End Code: '0x8302']

     • Fatal CPU Unit error.[End Code: '0x0080']

     • Non-fatal CPU Unit error.[End Code: '0x83C2']


  • Fixed Address Hints for the C500 IR register.
  • Added 2 new string types:

    • XXX as string with Only the Low Order byte (LSB - least significant 8-bits) of each word is used for

      read/write. , Syntax: XXXaddr.lenE

    • XXX as string with Only the High Order byte(MSB - most significant 8-bits) of each word is used for

      read/write. , Syntax: XXXaddr.lenD
